Glufosinate (siehe Formel (Ia)) ist der Kurzname oder "common name" für den
Wirkstoff (D,L)-2-Amino-4-[Hydroxy-(methyl)phosphinyl]-butansäure, der als
Monoammoniumsalz kommerziell erhältlich ist und als Blattherbizid eingesetzt wird
(siehe DE-A-27 17 440).
Glufosinate (see formula (Ia)) is the short name or "common name" for the active ingredient (D, L) -2-amino-4- [hydroxy- (methyl) phosphinyl] butanoic acid, which is commercially available as the monoammonium salt and as Leaf herbicide is used (see DE-A-27 17 440).
Das Herbizid kann zur nicht-selektiven Bekämpfung von Unkräuter im Obst- und Weinbau, in Plantagekulturen, im Gemüsebau vor der der Aussaat oder dem Verpflanzen, vor der Direktsaat von Mais oder Sojabohne sowie auf Nichtkulturland wie Wegrändern, Industriegelände und Bahnanlagen eingesetzt werden (vgl. Z. PflKrankh. PflSchutz, Sonderheft IX, 431-440, 1981). Bekannt ist auch der selektive Einsatz zur Bekämpfung von Unkräutern in gentechnisch resistent gemachten Nutzpflanzenkulturen wie Mais und Raps u. a. (vgl. EP-A-242246).The herbicide can be used for non-selective weed control Fruit and wine growing, in plantation crops, in vegetable growing before sowing or transplanting, before direct sowing of maize or soybean and on Non-cultivated land such as roadsides, industrial sites and railways (see Z. PflKrankh. PflSchutz, Special Issue IX, 431-440, 1981). Is known also the selective use to control weeds in genetic engineering crops made resistant such as maize and oilseed rape u. a. (see EP-A-242246).
Eine Vielzahl von Verfahren zur Herstellung von Glufosinate sind bekannt. Nach der
in EP-A-0011245 beschriebenen Variante lassen sich phosphorhaltige
Cyanhydrinderivate der Formel
A variety of processes for the production of glufosinates are known. According to the variant described in EP-A-0011245, phosphorus-containing cyanohydrin derivatives of the formula can be used

Haloalkyl, Cycloalkyl, Phenyl oder Benzyl ist, R' Wasserstoff, Alkyl, Phenyl oder
Benzyl und R'' Wasserstoff, Acyl, Trialkylsilyl oder Alkylsulfonylalkyl bedeuten,
in Aminonitrile überführen, die ihrerseits zu Glufosinate hydrolysiert werden können.
Die Herstellung der Cyanhydrinderivate erfolgt nach EP-A-0011245 durch Reaktion
eines Methanphosphonigsäuremonoalkylesters und eines
Acroleincyanhydrinderivats der Formel
wherein R is an optionally substituted hydrocarbon radical such as alkyl, haloalkyl, cycloalkyl, phenyl or benzyl, R 'is hydrogen, alkyl, phenyl or benzyl and R''is hydrogen, acyl, trialkylsilyl or alkylsulfonylalkyl, converted into aminonitriles, which in turn are hydrolyzed to glufosinates can. The cyanohydrin derivatives are prepared according to EP-A-0011245 by reacting a monoalkyl methanephosphonite and an acrolein cyanohydrin derivative of the formula
worin R' und R'' die obengenannte Bedeutung haben. Das beschriebene Verfahren hat den Nachteil, daß das phosphorhaltige Derivat und dessen Vorstufen in Form von Estern bereitgestellt werden müssen, obwohl im gewünschten Produkt Glufosinate der Hydroxymethylphosphinylrest in hydrolysierter Form vorliegt.wherein R 'and R' 'have the meaning given above. The procedure described has the disadvantage that the phosphorus-containing derivative and its precursors in the form must be provided by esters, although in the desired product Glufosinate of the hydroxymethylphosphinyl residue is in hydrolyzed form.

Die Verbindungen der allgemeinen Formel III sind Basischemikalien und deshalb ebenfalls bekannt.The compounds of general formula III are basic chemicals and therefore also known.
Die in der Reaktionsfolge durchlaufenen 2-Methyl-1,2-oxa-4-phospholene der allgemeinen Formel IV und die Aminonitrile der Formel (V) sind bisher unbekannt und daher ebenfalls Gegenstand der vorliegenden Erfindung.The 2-methyl-1,2-oxa-4-phospholenes passed through in the reaction sequence general formula IV and the aminonitriles of formula (V) are hitherto unknown and therefore also the subject of the present invention.
Von den 1,2-Oxa-4-phospholenen sind lediglich einige höhere Homologe bekannt.
setzt sich Phenyldichlorphosphan (IIa) mit α,β-ungesättigten Ketonen (VI) unter
Zusatz von Acetanhydrid zu den 2-Phenyl-2-oxo-1,2-oxa-4-phospholenen (VII) um
(K. Bergesen, Acta Chem. Scand. 19, 1784 (1965)),
Of the 1,2-oxa-4-phospholenes, only a few higher homologs are known. Phenyldichlorophosphane (IIa) reacts with α, β-unsaturated ketones (VI) with the addition of acetic anhydride to the 2-phenyl-2-oxo-1,2-oxa-4-phospholenes (VII) (K. Bergesen, Acta Chem Scand. 19, 1784 (1965)),
worin R3 und R4 Wasserstoff, Methyl oder Phenyl und R5 Methyl oder Phenyl bedeuten.wherein R 3 and R 4 are hydrogen, methyl or phenyl and R 5 is methyl or phenyl.
Weiterhin ist bekannt, daß Ethyldichlorphosphan IIb mit Methylvinylketon (VIa) zu 5-Methyl-
2-ethyl-2-oxo-1,2-oxa-4-phospholen (VIIa) reagiert (A. N. Pudovik et al., Isv.
Akad. Nauk. SSSR, Ser. Khim. (engl. Fassung) 2543 (1970));
Et = Ethyl in Formel IIb; Me = Methyl in Formel VIIa; Ac = Acetyl;
It is also known that ethyl dichlorophosphane IIb reacts with methyl vinyl ketone (VIa) to give 5-methyl-2-ethyl-2-oxo-1,2-oxa-4-phospholene (VIIa) (AN Pudovik et al., Isv. Akad. Nauk SSSR, Ser. Khim. (English version) 2543 (1970));

Analoge Umsetzungen, z. B. mit dem im Vergleich zu Phenyldichlorphosphan hochreaktiven Methyldichlorphosphan (vgl. H. Heydt et al., Methoden der Organischen Chemie XII E2, S. 29 (1982)) bzw. Methanphosphonigsäurediestern sind in der Literatur bislang nicht beschrieben worden. Auch analoge Umsetzungen mit Acrolein (III; R2 = H) sind nicht bekannt. Wegen der viel reaktiveren Komponenten II und III ist es überraschend, daß sie erfindungsgemäß in übersichtlicher Weise und hohen Ausbeuten zu den Intermediaten IV reagieren, die dann auf die beschriebene Weise über die α-Aminonitrilderivaten V zu den Verbindungen I umgesetzt werden können.Analogous implementations, e.g. B. with compared to phenyldichlorophosphane highly reactive methyldichlorophosphane (see H. Heydt et al., Methods of Organic Chemistry XII E2, p. 29 (1982)) or methanephosphonous diesters have not been described in the literature. Analogous reactions with acrolein (III; R 2 = H) are also not known. Because of the much more reactive components II and III, it is surprising that according to the invention they react in a clear manner and in high yields to the intermediates IV, which can then be converted to the compounds I in the manner described via the α-aminonitrile derivatives V.
Das erfindungsgemäße Verfahren wird in Stufe 1 im allgemeinen so durchgeführt, daß man Verbindungen der allgemeinen Formel II mit ungesättigten Verbindungen der allgemeinen Formel III, vorzugsweise in Gegenwart eines Kondensationsmittels, umsetzt. Als Kondensationsmittel eignen sich Stoffe, welche die Abgangsgruppen R1 und R2 bzw. die Verbindungen R1-H und R2-H binden. Geeignete Kondensationsmittel sind Carbonsäureanhydride wie Essigsäureanhydrid, und Propionsäureanhydrid.The process according to the invention is generally carried out in stage 1 by reacting compounds of the general formula II with unsaturated compounds of the general formula III, preferably in the presence of a condensing agent. Suitable condensing agents are substances which bind the leaving groups R 1 and R 2 or the compounds R 1 -H and R 2 -H. Suitable condensing agents are carboxylic anhydrides such as acetic anhydride and propionic anhydride.
Die Umsetzung von Verbindungen II und III kann ohne Lösungsmittel oder in Gegenwart eines organischen Lösungsmittels, z. B. aliphatischen oder aromatischen Kohlenwasserstoffen, die gegebenenfalls halogeniert sind, wie Dichlormethan, Toluol, Xylol, Chlorbenzol, oder Ethern wie Dioxan oder Alkoholen wie Ethanol, n-Butanol etc. oder Gemischen dieser exemplarischen Lösungsmittel erfolgen.The reaction of compounds II and III can be carried out without solvent or in Presence of an organic solvent, e.g. B. aliphatic or aromatic Hydrocarbons which are optionally halogenated, such as dichloromethane, Toluene, xylene, chlorobenzene, or ethers such as dioxane or alcohols such as ethanol, n-butanol etc. or mixtures of these exemplary solvents.
Die Phosphorkomponenten der allgemeinen Formel II werden in Molverhältnissen eingesetzt die von der Stöchiometrie weit abweichen können, vorzugsweise in Molverhältnissen von 1 : 2 bis 2 : 1, insbesondere jedoch in äquimolaren Mengen, bezogen auf die Komponente III, eingesetzt.The phosphorus components of the general formula II are in molar ratios used which can deviate widely from the stoichiometry, preferably in Molar ratios of 1: 2 to 2: 1, but especially in equimolar amounts, based on component III, used.
Wenn die Umsetzung der Komponenten II und III in Gegenwart eines Anhydrids, wie z. B. Essigsäureanhydrid oder Propionsäureanhydrid durchgeführt wird, sind in der Regel Einsatzmengen des Anhydrids im Bereich von über 0 bis 400 Mol-%, vorzugsweise Mengen von 50 bis 150 Mol-%, bezogen auf die Ausgangskomponenten II und III geeignet. If the reaction of components II and III in the presence of an anhydride, such as e.g. B. acetic anhydride or propionic anhydride are in the Rule quantities of the anhydride in the range from over 0 to 400 mol%, preferably amounts of 50 to 150 mol%, based on the Starting components II and III suitable.
Die erfindungsgemäße Umsetzung der Verbindungen II und III gelingt in der Regel bei Reaktionstemperaturen zwischen -80°C und +200°C, vorzugsweise zwischen -10°C und +60°C. Die Reaktionsdauer liegt beispielsweise im Bereich von 0,5-48 Stunden (h), vorzugsweise 0,5-18 h.The reaction of the compounds II and III according to the invention is generally successful at reaction temperatures between -80 ° C and + 200 ° C, preferably between -10 ° C and + 60 ° C. The reaction time is, for example, in the range of 0.5-48 Hours (h), preferably 0.5-18 h.
Die erfindungsgemäße Umsetzung der Zwischenverbindungen IV zu den gewünschten α-Aminonitrilen V (Stufe 2) kann überraschenderweise unter Bedingungen durchgeführt werden, wie sie analog zur Herstellung von Aminonitrilen aus Aldehyden oder Ketonen nach dem Typ der "Strecker-Synthese" bekannt sind (siehe Lehrbücher und Handbücher der organischen chemischen Synthese). Nach einer möglichen Verfahrensweise wird die das Rohprodukt IV enthaltende Reaktionslösung zu einer Lösung oder Suspension aus einem Alkalicyanid und Ammoniumchlorid in wäßriger Ammoniaklösung gegeben wird.The inventive implementation of the intermediate compounds IV to desired α-aminonitrile V (stage 2) can surprisingly below Conditions are carried out as they are analogous to the production of amino nitriles from aldehydes or ketones according to the type of "Strecker synthesis" are known (see textbooks and manuals of organic chemical synthesis). After One possible procedure is that of the crude product IV Reaction solution to a solution or suspension of an alkali metal cyanide and Ammonium chloride is given in an aqueous ammonia solution.
Hierbei können auch Gemische mit den bereits genannten organischen Lösungsmitteln, wie z. B. Toluol, Xylol, Chlorbenzol, Dichlormethan Ethanol Butanol etc. eingesetzt werden. Anstelle von Alkalicyaniden können auch Erdalkalicyanide oder Ammoniumcyanid, oder Lösungen von Blausäure in Ammoniak eingesetzt werden.Mixtures with the already mentioned organic ones can also be used here Solvents such as B. toluene, xylene, chlorobenzene, dichloromethane ethanol butanol etc. are used. Instead of alkali metal cyanides, alkaline earth metal cyanides can also be used or ammonium cyanide, or solutions of hydrocyanic acid in ammonia become.
Die Cyanide bzw. die Blausäure werden z. B. in Mengen von 80-130 Mol-% bevorzugt jedoch in äquimolaren Mengen, bezogen auf die Komponenten der Formel IV, eingesetzt. Die auf die Verbindung IV bezogene Ammoniakmenge beträgt beispielsweise zwischen 100 und 800 Mol-%, bevorzugt 100 bis 400 Mol-%. Die Umsetzungen der Verbindungen IV nach den Bedingungen der Strecker- Synthese werden beispielsweise bei -10°C bis 100°C, vorzugsweise bei 0-45°C durchgeführt.The cyanides or hydrocyanic acid are, for. B. in amounts of 80-130 mol% however, preferably in equimolar amounts, based on the components of the Formula IV used. The amount of ammonia related to compound IV is, for example, between 100 and 800 mol%, preferably 100 to 400 mol%. The reactions of the compounds IV according to the conditions of the stretchers Synthesis are for example at -10 ° C to 100 ° C, preferably at 0-45 ° C. carried out.
Die Verbindungen der Formel V werden vorzugsweise als Salze erhalten, in denen das acide Wasserstoffatom an der Phosphinoylgruppe durch ein Kationenäquivalent, vorzugsweise ein Kationenäquivalent wie z. B. Li⁺, Na⁺, K⁺, (Mg2⁺)½, (Ca2⁺)½, NH4⁺ ersetzt ist. The compounds of formula V are preferably obtained as salts in which the acidic hydrogen atom on the phosphinoyl group by a cation equivalent, preferably a cation equivalent such as. B. Li⁺, Na⁺, K⁺, (Mg 2 ⁺) ½ , (Ca 2 ⁺) ½ , NH 4 ⁺ is replaced.
Alternativ können die Zwischenverbindungen IV durch Destillation oder extraktive Methoden zunächst gereinigt werden und in gereinigter Form zu den Aminonitrilen V umgesetzt werden.Alternatively, the intermediates IV can be obtained by distillation or extractive Methods are first cleaned and in purified form to the aminonitriles V be implemented.
In einer weiteren Variante werden die Zwischenverbindungen IV zunächst mit
Wasser zu den Aldehyden bzw. Ketonen der allgemeinen Formel IV' hydrolysiert
und in einem weiteren Schritt zu den α-Aminonitrilen V umgesetzt.
In a further variant, the intermediate compounds IV are first hydrolyzed with water to give the aldehydes or ketones of the general formula IV 'and, in a further step, converted to the α-aminonitriles V.
In der allgemeinen Formel IV' bedeutet R* Wasserstoff oder (C1-C4)-Alkyl, vorzugsweise Methyl. Die Verbindung mit R* = Wasserstoff ist in der Methylphosphinsäurereihe neu und daher ebenfalls Gegenstand der Erfindung. Die Verbindung IV mit R* = Methyl ist bekannt (L.D. Quin et al., J. Org. Chem. 39, 686 (1974)).In the general formula IV ', R * is hydrogen or (C 1 -C 4 ) alkyl, preferably methyl. The compound with R * = hydrogen is new in the methylphosphinic acid series and is therefore also an object of the invention. The compound IV with R * = methyl is known (LD Quin et al., J. Org. Chem. 39, 686 (1974)).
Gemäß Stufe 3 des erfindungsgemäßen Verfahrens stellen die α-Aminonitrile der allgemeinen Formel V wertvolle Vorprodukte dar, die sich analog literaturbekannten Verfahrensbedingungen (Houben-Weyl, Methoden der Organischen Chemie XI/2, S. 305 und S. 371, 1958) sowohl im sauren wie auch im alkalischen Medium zu den biologisch aktiven Aminosäuren der Formel I, insbesondere zu Glufosinate der Formel Ia verseifen lassen.According to stage 3 of the process according to the invention, the α-aminonitriles are general formula V are valuable preliminary products which are known analogously to the literature Process conditions (Houben-Weyl, Methods of Organic Chemistry XI / 2, P. 305 and p. 371, 1958) in both the acidic and the alkaline medium biologically active amino acids of formula I, in particular to glufosinates Have formula Ia saponified.
Im Vergleich zu bekannten Verfahren zur Synthese der herbiziden Aminosäure Ia weist das erfindungsgemäße Verfahren einige Vorteile auf, z. B. kommt es ohne zusätzliche Veresterung der Phosphorkomponenten der Vorprodukte IV, IV' und V der Vorprodukte aus. Außerdem kann das Verfahren wahlweise in jeder Stufe separat oder über alle 3 Stufen als Eintopfverfahren durchgeführt werden. Compared to known methods for the synthesis of the herbicidal amino acid Ia the method according to the invention has some advantages, e.g. B. it comes without additional esterification of the phosphorus components of the precursors IV, IV 'and V of the intermediate products. In addition, the process can be carried out at any stage be carried out separately or over all 3 stages as a one-pot process.
So kann die essentielle PC-Verknüpfung zum Aufbau der Aminosäureseitenkette in einem Schritt z. B. mit Methyldihalogenphosphanen bzw. Methanphosponigsäurediestern II und Olefinen III durchgeführt werden, ohne das eine aufwendige Umarbeitung z. B. von Methyldichlorphosphan zu Methanphosponigsäurenmonoestern nötig ist. Außerdem wird im Vergleich zu dem aus EP-A-001124511 bekannten Verfahren die radikalische Addition der Methanphosphonigsäuremonoester an Acroleinderivate vermieden, die leicht zu Nebenprodukten führt.The essential PC link for building the amino acid side chain in a step z. B. with methyl dihalophosphines or Methanephosphonic acid diesters II and olefins III are carried out without the a complex reworking z. B. of methyldichlorophosphine Methane phosphonic acid monoesters is necessary. It also compares to that processes known from EP-A-001124511 the radical addition of Methanephosphonous monoesters avoided on acrolein derivatives, which are easy to By-products leads.
Bei dem erfindungsgemäßen Verfahren können z. B. die einfach zugänglichen Olefinkomponenten Acrolein bzw. Methylvinylketon direkt ohne notwendige Derivatisierung eingesetzt werden. Weiterhin fallen bei dem erfindungsgemäßen Verfahren die α-Aminonitrile V mit freier Phosphinsäure- bzw. Phosphinatgruppierung an, so daß im letzten Syntheseschritt lediglich die Nitrilgruppe zur freien Aminosäure verseift werden muß. Die beim genannten herkömmlichen Verfahren erforderliche Deblockierung der Phosphinestergruppe zur freien Phosphinsäure ist damit überflüssig.In the method according to the invention, for. B. the easily accessible Olefin components acrolein or methyl vinyl ketone directly without necessary Derivatization can be used. Furthermore fall with the invention Process the α-amino nitriles V with free phosphinic acid or Phosphinate grouping, so that in the last synthesis step only the Nitrile group must be saponified to the free amino acid. The one mentioned Conventional processes required deblocking of the phosphine ester group free phosphinic acid is therefore superfluous.
Die nachfolgenden Beispiele erläutern das Verfahren, ohne daß damit eine Einschränkung der möglichen Verfahrensbedingungen gemeint ist.The following examples illustrate the process without this Restriction of the possible process conditions is meant.
